Prunus persica

VARIETY DENOMINATION

‘Supechseventeen’

BACKGROUND AND SUMMARY OF THE INVENTION

This invention relates to the discovery and asexual propagation of a new and distinct variety of peach, Prunus persica cv. ‘Supechseventeen’. The new variety was first hybridized in 2001 and selected in 2003 by Terry Bacon as breeder number: ‘PE386’. The new variety was first evaluated by Terry Bacon near Wasco, Calif. in Kern County. The variety ‘Supechseventeen’ was originated by hybridization.

The new variety ‘Supechseventeen’ is characterized by its large size, dark over-color and early harvest.

The seed parent is ‘Supechsix’ (the subject of U.S. Plant Pat. No. 11,631), and the pollen parent is ‘91-006C’ (an unpatented Sun World peach). The parent varieties were first crossed in February 2001, with the date of planting of the progeny being February 2002, and the date of first flowering being February 2003. The new peach variety ‘Supechseventeen’ was first asexually propagated by Terry Bacon near Wasco, Kern County, Calif. in January 2005, by budding.

The new variety ‘Supechseventeen’ is distinguished from its seed parent, ‘Supechsix’, in that the fruit of the new variety ripens about five days later than that of ‘Supechsix’ and has darker over-color. The fruit of the new variety ‘Supechseventeen’ is larger in diameter than that of ‘Supechsix’, at about 65 mm in comparison to 64 mm.

The fruit of the new variety ‘Supechseventeen’ is distinguished from that of its pollen parent, ‘91-006C’, in that the fruit of the new variety ripens about four days later than that of ‘91-006C’ and has melting flesh while the fruit of ‘91-006C’ has non-melting flesh. The fruit of the new variety ‘Supechseventeen’ is also larger in diameter than that of ‘91-006C’, at about 65 mm in comparison to 63 mm.

The fruit of the new variety ‘Supechseventeen’ ripens at nearly the same time as that of ‘Super Rich’ (U.S. Plant Pat. No. 9,860), but is larger in size at about 65 mm in comparison with 63 mm of ‘Super Rich’. The fruit of the new variety also has darker over-color than that of ‘Super Rich’. The fruit of the new variety is also similar in appearance and shape to the fruit of ‘Crimson Lady’ (U.S. Plant Pat. No. 7,953), but its harvest starts about 20 days earlier.

The new variety ‘Supechseventeen’ has been shown to maintain its distinguishing characteristics through successive asexual propagations by, for example, budding.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Throughout this specification, color names beginning with a small letter signify that the name of that color, as used in common speech is aptly descriptive. Color names beginning with a capital letter designate values based upon the R.H.S. Colour Chart published by The Royal Horticultural Society, London, England.

The descriptive matter which follows pertains to 4 year old ‘Supechseventeen’ plants on Nemared (unpatented) rootstock, grown in the vicinity of Wasco, Kern County, Calif., during 2009, and is believed to apply to plants of the variety grown under similar conditions of soil and climate elsewhere.
